Fixing Python Performance with Rust

The Sentry team has successfully replaced their Python-based source map processing with a Rust module, significantly reducing processing times and CPU utilization. The switch was made due to Python's shortcomings in handling the complexity of modern source maps, which led to a bottleneck in their system. The Rust solution, built using CFFI, allows for efficient parsing and processing of source maps, making it an ideal choice for this task. The Sentry team has also developed a thin wrapper around the Rust library, providing a Python API that integrates seamlessly with their existing codebase. This project demonstrates the potential of Rust as a tool for optimizing performance-critical components in Python-based systems.
